To all whom it may 0011,0117

Beit known that 1, WILLIAM KIRKPAirnioK BRYCE, a subject ol the King of Great Britain, residing at Winnipeg, county of Selkirk, in the Province oi Manitoba, in the Dominion of Canada, have invented certain new and useful Improvements in Switch-Rods; and I do hereby declare that the following is a lull, clear, and exact description oil? the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to railroad-switches.

The object of my invention is to provide a switch-rod which is extensible in two directions and adapted to prevent the breakage of switch-points, switch-rods and switch-stands by the passage of a traim over the switch when. it is not properly set.

A. further object of my invention is to provide means in a device oi? the character mentioned which will effectually prevent bind.- ing oi the movable parts.

A :lurther object of my invention is to provide a construction in such a device that will. not require the spring used to be pressed or wound rigidly to any of the parts; and my invention. consists oi" the construction, comhination, and arrangement ol parts, as herein illustrated and described.

in the accompanying drawings, forming a part 01'' this application, I have illustrated one form of embodiment of my invention, in which drawings similar reference-numerals design ate corresponding parts, and in. which Figure 1 is a top plan view showing the application of my invention. Fig. 2 is an enlarged plan view of my invention. Fig. 3 is a vertical section, taken longitudinally, of my invention on the line 3 3 of Fig. 2. Fig. 4!; is a vertical section, taken transversely, of my invention on the .line l 4: of Fig. 2; and Fig. 5 is a perspective view of one oi" the slidable members oi my invention, the other parts being 1'611'10'V6Ll. to show the construction.

Referring to the drawings, (5 6 are oppositelydisposed, similarly-tormed members, preferably cylindrical in shape, in. which are formed the slots 7 7,e.\'tending longitudinally :lrorn one end thereof, which slots each comprise a segment of approximately ninety degrees of the circumference of said member and extend radially from. its axis and which slots terminate in shoulders 8 8, termed integrail with the body of saic. members.

These form the shoulders l) 9 and. in their slotted ends are each provided with a tapered. opening 10, extending entirely through. the menu her at that point. Disposed against each of the shoulders fl 9 is a washer 11, against which. washers thrust the opposite ends of a helical spring 12, which is so formed that it exerts an equal pressure on the washer all. the way around. the member 6 when the members 6 6 are pulled apart, a cotter 13 being insorted in the openings 10, which cotter bears against its adjacent washer and is provided with a split pin i l, adapted to retain it in position. it is evident from the drawings that the shoulders 9 resist the pressure of the spring 12 when the members 6 6 are forced toward. each other.

In the drawings 15 15 are the rails of a main track.

16 16 are the rails of a siding, to the latter of which. is connected in any suitable way a switch-rod 17. One end of my invention. is attached to the outer end ol the switch-rod, as by the rivet 1.8, this end of my .invention. being :llattened for that purpose, as seen. at 19, Fig. The opposite end of my invention is secured in any suitable way to a switchthrowing lever :50 of ordinary con-- struction.

in the operation. of my invention it is obvious that when a train from a siding passes to the main track the switch-tongue 1.5 will be thrown out of the way by the llanges of the Wheels, and as soon as the train has passed. the switch-tcmgue will resume its normal posi tion -that illustrated in Fig. 1. When the switch is thrown to its other position, a train passing over the switch will throw the switch-- tongue 16 in an opposite direction. Otherwise its operation is the same. As the spring 12 is not rigidly connected to any of the parts, there will be no binding when the spring compressed in either direction.

While l. .have shown in the accompanying drawings the preferred YiOllll of my invention, it will be urnlcrstood that .l. do not limit .urysell'" to the precise form shown, as many of the details may be changed in :lorm or position without affecting the operativeness or utility of my invention or departing from the spirit of the invention thereof.

Therefore I reserve the right to makei' all such modifications as are included within the scope of the following claims or of mechanical equivalents to the structure set forth.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

1. A switch-rod comprising a plurality of interlocked members, a spring disposed on said members, and members contacting with said spring, and adapted to maintain it in position.

2. A switch-rod comprising a plurality of longitudinally-s10tted interlocked members,

a spring disposed on said members, and

members contacting with said spring, and adapted to maintain it in position.

3. switch-rod comprising a plurality of interlocked members, each provided with a slot extending radially from its axis, a spring disposed on said members, and members contacting with said spring, and adapted to maintain it in position.

4. A switch-rod comprising a plurality of interlocked members, each provided with a plurality of segment-shaped slots extending radially from its axis, a spring disposed on said members, and members contacting with said spring, and adapted to maintain it in position.

5. A switch-rod comprising a plurality of interlocked members, each. provided with a plurality of segment-shaped slots, each of said slots comprising ninety degrees of the circumference of said members and extending radially from the axis thereof, aspring disposed on said members, and members contacting with said spring, and adapted to maintain it in position.

6. A switch-rod comprising a plurality of interlocked members, provided with longitu dinal slots, each terminating in a shoulder, a spring disposed on said members, and members contacting with said spring, and adapted to maintain it in position.

7. A switch-rod comprising a plurality of interlocked members, each provided with lon gitudinal slots which terminate in a shoulder integral with said member, a spring disposed on said members, and members contacting with said spring, and adapted to maintain it in position.

8. A switch-rod comprising a plurality of slidably-interlocked members, a spring dis posed on said members, and members con tacting with said spring, and adapted to maintain it in position.

9. A switch-rod comprising a plurality of slidably-interlocked, slotted members, each provided with an exterior shoulder, a spring disposed on said members, washers disposed on said members intermediate of the ends of said spring and said shoulders, and means carried by said members to compress said spring.

10. A switch-rod comprising a plurality of slidably-interlocked, slotted members, each provided with an exterior shoulder, a spring disposed on said members, washers disposed on said members intermediate of the ends of said spring and said shoulders, and a projecting member carried by said members to compress said spring.

11. A switch-rod comprising a plurality of slidably-interlocked, slotted members, each provided with an exterior shoulder, a spring disposed on said members, washers disposed on said members intermediate of the ends of said spring and said shoulders, and a cotter carried by said members to compress said spring.

12. A switch-rod comprising a plurality of slidably-interlocked, slotted members, each provided with an exterior shoulder, a spring disposed on said members, washers disposed on said members intermediate of the ends of said spring and said shoulders, a cotter carried bysaid members to compress said spring, and a split pin adapted to secure said cotter in position.

13. In a device of the character described, a switch and a switch-throwing member, in combination with a plurality of slotted mem bers, a spring disposed on said slotted members, and contacting means, adapted to compress the spring in a plurality of directions, one of said members being connected with the switch and the other of said members being connected with the switch-throwing member.

In witness whereof I have hereunto set my hand in the presence of two witnesses.
